recensies: Perfect being identical to the military version from ww2. That being said these are nearly identical with the only real difference being the cap & air vent. I like the new air vent better!
They seal with a replaceable o-ring.
The spout is plastic and free of the rediculous "safety" mechanism that usually makes things worse!
Well constructed & shipped fast.
I bought two & will be buying two more!

recensies: Designed like the proven successful U.S. Military "Jerry Can" that had been used for Decades. Many of the U.S. Military Jerry Cans of this Design have lasted for Many Decades of Use.
Has mostly metal parts, that do not crack nor break easily like Plastic Cans. Only the nozzle and the vent cap knob are plastic. The rest are Highly durable aluminum or steel.
Does have a screw in Vent that allows for pouring without "Vapor Lock"; so less spills.
The screw in Vent can be used to allow for liquid heat expansion and or vapor to prevent "bulging" unlike most Plastic Cans with no Vent that crack during liquid heat expansion or vapor expansion.
Uses common sized O-Rings for seals
Has a metal (Aluminum) cap and the portion that connects (screws in) the plastic nozzle to the Can is also metal (Aluminum) not fragile plastic. The bottom half of the Vent knob that screws into the Can is steel with a slot vent.
This sized 5 Gallon, 20 Liter Can should fit most Military Vehicle Mounted Brackets.
After receiving, tested for leaks; none.
